To Obama, on jobs: Mr. President, your campaign is currently running a television ad in which you promise to create 1 million new manufacturing jobs in your second term. Four years ago, you promised to create 5 million new green energy jobs, but fewer than 5,000 have actually come into being, and there are now 261,000 fewer jobs overall than when you were inaugurated. What makes your new job-creation promise any more credible than the old one?

To Romney, on spending: You have said you will not cut defense spending, nor Medicare, nor Social Security benefits for those within 10 years of enrolling. These promises, combined with interest payments on the national debt, would place about 70 percent of the federal budget off limits for cuts by the end of the decade. How can you then promise to balance the budget by 2020, given that you have also promised not to raise taxes?

To Obama, on health care: When Congress passed your health care law, you promised that it would make insurance premiums for families go down by $2,500 per year. Yet since the bill passed, premiums have actually risen, on average, by nearly that same amount. If your health care law is failing to make insurance more affordable for families, why should Americans think it more likely to accomplish its other stated goals?
